Circular Reference No.: CNB/227A

All Importers, Exporters, Traders, Freight Forwarders, Declaring Agents, Cargo Agents and Carriers of 4-Anilino-N-phenethylpiperidine (ANPP) and N-Phenethyl-4-piperidone (NPP)

Scheduled substances controlled by Director, Central Narcotics Bureau (CNB)

  1. CNB is the approving authority for controlled substances listed in the Third Schedule of the Misuse of Drugs Act (MDA) since 5 September 1999. A circular dated 31 August 1999, which includes a list of the controlled substances, has been circulated to all traders. For easy reference, the updated controlled substances list as of 1 Nov 2017 is enclosed at Annex A.

  2. As of 1 Nov 2017, 4-Anilino-N-phenethylpiperidine (ANPP) and N-Phenethyl-4-piperidone (NPP) will be included in Part 1 of the Third Schedule under the Misuse of Drugs Act (MDA) Chapter 185.

  3. With this inclusion, the manufacture, supply, possession, import or export of 4-Anilino-N-phenethylpiperidine (ANPP) and N-Phenethyl-4-piperidone (NPP) for the purpose of manufacturing of a controlled drug, would contravene Section 10A of the MDA. Any person convicted of this offence shall be punished with imprisonment not exceeding 20 years or with a fine not exceeding $200,000 or with both. Persons found to have imported or exported this substance without a permit from CNB can be prosecuted under Misuse of Drugs (Controlled Equipment, Material and Substances) Regulations and punishable with imprisonment not exceeding 3 years or with a fine not exceeding $10,000 or with both.

  4. With effect from 1 Nov 2017, traders intending to import, export or transship 4-Anilino-N-phenethylpiperidine (ANPP) and N-Phenethyl-4-piperidone (NPP) shall declare to CNB 14 days before the effective date of import, export or transshipment.

  5. CNB is the approving authority for the import, export and transship of 4-Anilino-N-phenethylpiperidine (ANPP) and N-Phenethyl-4-piperidone (NPP). They are currently declared under HS code 29333990, depending on the product descriptions.

  6. With effect from 1 Nov 2017, in addition to HS codes, traders and declaring agents are required to indicate “CNB” as the approving authority under the Customs Procedure Code (CPC) field in your permit application submitted in TradeNet®.

  7. The new requirement for CPC is introduced to facilitate the processing of your import/export/transshipment permit applications submitted for products that contain CNB controlled substances but are not classified under CNB controlled HS codes.
